Reproducible gtk crash

[Simon Josefsson]

Shortly after the last crash, I got another one...

This crash seem reproducible, I rebuilt today's CVS and still get the
problem.

The crash happen when I click "Save" on a MIME attachment in Gnus, and
Emacs is popping up a GTK Save As Dialog.  It crashes, with the
backtrace below.

This is on an up to date Debian testing x86 machine.
